COMBINED GAGE AND CUTTER MECHANISM.

To all whom it may concern:

Be it known that I, VILLIAM Gr. PERKINS, residing at Brooksville, in thecounty of Hernando and State of Florida, have invented anew and ImprovedCombined Gage and Cutter Mechanism, of which the following is aspecification.

My invention has for its object to provide a simple, inexpensive andeasily manipulated mechanism in the nature of a combined adjustableguide and planer means for saw mill carriages, and it consists in thepeculiar arrangement and novel combination of parts hereinafter fullydescribed, specifically set out in the appended claim and illustrated inthe accol'npanying drawing, in which Figure 1, is a perspective view ofmy invention showing the same arranged as a planer. Fig. 2, is a similarview showing it arranged as a guide or gage. Fig. 3, is a longitudinalsection thereof. Fig. 4, is a detail view of one end of the carryingheads with the removable bearing members.

In the practical arrangement of my machine, the base is formed ofparallel longitudinally extended members 1-1, each consisting of anupper and a lower bar 10-10, separated at the front ends by space blocks11 and at the rear ends by a cross bar 12 having a central aperture 13,the purpose of which will presently appear, the said members 1010, 11and 12 being suitably bolted together to form a strong base withelongated horizontal slots 14- 1t.

2 designates a carriage composed of the upper and lower heads 20 20joined by the vertical standard 21. the lower head having a pendent leg22 laterally extended to form slides 2323 for riding in the slots14.-14.

The front edges of the heads 20-20 are in vertical alinement and are ina plane at right angles to the longitudinal axis of the bed so as topresent a bearing in a plane parallel with the edge of the timber thatis held up to the gage as it is fed to or from the saw.

In the construction shown, the opposite ends of the heads have slot-Ways2525 to receive removable bra-sses or bearings 26 26 so that either thejournals of guide roll- Specification of Letters Patent.

ers 24t-2at or the journals of a planer or cutter head (see Fig. 1) canbe interchangeably mounted in either or both ends of the heads. Vhenused as a planer but one cutter head is preferably .used, as shown inFig. 1, the roller at the other end forming a guide for the lumber beingtrimmed, and the shaft 27 of the cutter extends below the base 1 andcarries a belt pulley 28 around which takes a drive belt 29 that takesaround a drive pulley 30 which, in the practical application of myinvention, may be friction or otherwise clutched with a pulley drivefrom the saw arbor, in the well-known manner.

31-31 designate a pair of segmental racks mounted on the parallel sidemembers of the base with which coacts a pawl 32 slidably mounted on thesetting lever 33. To provide for adjusting the sweep movements of thelever so my invention may be readily adapted for getting the proper setand gage for the size of lumber desired to cut, I mount the said lever33 in the manner best shown in Fig. 3, by reference to which it will beseen the lower end of the lever fulcrums on a rod 35 adjustably mounted011 the base frame and whose outer end extends through the aperture 13in the base and is threaded to receive the adjusting nut 36 and jam nut37, it being obvious that by proper adjustment of the said nuts the headstock can be first set to accommodate the general different sizes oftimber and after set, can be adjusted to suit the exact sizes to beplaned or held for the trimmer saws.

From the foregoing, taken in connection with the drawing, the completearrangement, the manner of operation and the advantages of my invention,are apparent and need not be further specified.

Having thus described my invention, what I claim is:

A mechanism of the character stated that comprises a base formed of twosets of parallel bars and spacing blocks between the bars.

of a set to separate the same, said pairs of bars being spaced one pairfrom the other to leave a central passageway, a cross plate projectedthrough said pairs of bars and slidable therein, a guide and cuttercarriage mounted on the top of said pairs of bars and connected withsaid slidable plate, a lever whose lower end is projected into thecentral passage between said pair of bars, a shiftable fulcrum for saidlever, a connection between said lever and said guide and cuttercarriage shifting plate, and rack segments w.
